A woman holds the body of her infant who was killed in an Aleppo airstrike

That is according to Stephen O’Brien, UN under-secretary-general for humanitarian affairs who briefed the Security Council on Wednesday.

“For the sake of humanity we call on — we plead — with the parties and those with influence to do everything in their power to protect civilians and enable access to the besieged part of eastern Aleppo before it becomes one giant graveyard,” said O’Brien.

His plea comes as the White Helmet unit of volunteer rescuers said 51 mostly women and children were killed and over 50 wounded in the Jibb al-Qubba district.
